Hi all, found a great deal on a 75 gallon tank (under $300) complete with gravel, plants, equipment, even fish if I want some. I also currently have a 10 gallon tank with three male tequila sunrise delta guppies in it. So my question is: Should I keep the guppies in the 10 gallon (I'd like to keep it) or put them in the 75? Will this limit my options? Thanks!

Keep the guppies in the 10g. A 75g could have some huge fish in it, and most fish show aggression towards guppies, or eat them.

Make the 10 a shrimp only tank and put the Gups in the 75g. I have a 75g with nothing but Gups.
